I have a 2000 silverado 4wd GVWR 6400; GAWR Front axle 3925; Rear axle 3750 w\3.73 axle ratio; Max trailer #8500. It has Vortec 5300 w\tow package and Z71 suspension which someone told me was same suspension as 3/4 ton? I live in Colorado Springs. I am looking at the Fun Finder XT245 Toy hauler which is 27ft with Dry Wieght 4730 and GVWR 7840. I will carry 2 ATV = #1300. That leaves 1810 of cargo to max out to GVWR. Hitch weight = #3890 and I will install the Equalizer sway control hitch. If the trailer weighs the max 7840 am I pushing the envelope with my truck. Any help\personal experience will be appreciated.
